'luaa: pump pluugrrs '1' .worlc through stalling huxos S and inlzo plunger ma; 9 of pump casings 10, which latter are shown as rigidlf" secured on the top of the oil well casin The lower extremities of the pump p unger seats 9 are, as shown, connected to the upper ends of pipes 11, therlower ends of which terminate near the bottom of the oil well and are preferably provided with strainers l2.- Just above the upper ends of .the' pipes 11, the plunger seats 9 are equipped with gravity seated check valves 13. hove the valves 13, the plunger seats 9 are connected to oil discharge. ducts 14 formed in thepump casings 10 and terminating in thread cou- ,heads15. In the oil ducts 14 are seated check valves 16. The valves 3 on 16 cooperate with the pump plungers 7 in the customer way tolproduce a pump--. ing notion when t is said pum 'plun ers. are

reoiproouted. As is obrious,t e choc r valves '13 will open to permit the pum plungers to draw oil upward, and will c eck u reverse flow, while the valves 16 open to perunit the .011 to be disclnirged or forced on ward by the pump.

For the purposes of the following 'illus-f trations, puinps irom left toward the right,

- Figs..1:and 2, will be referred to as pum s Nos. 1, 2, 3 and 4.

It is evident that t e plunge'rs of the pumps 1 and 2 will be givenv downward or working strokes, while the ph n'gers of the pumps 3 and 4 are bein given upward or return movements, and vice versa, this being due to the arrangement of the eccentrics 3 and the described connections of the pump plungers thereto.

In carrying out'mymvention in connection with a. pump of the type, cbove described, pumps 1 and 3 are connected for 2.

common discharge, and pumps 2 and 4 are likewise connected for 'common discharge. This, as shown, is accomplished by providing oil deliver pipes 17 and 18, the former of which has ranches 17 connected to the coupling heads 15' of pumps 1 and 3, and the hitter of which has branches 18' connected to the coupling heads 15 of pumps 2 and 4. Of course, the said oil delivery pipes 17 nnd 18 muy have branches for delivering each to a multiplicity of bearings, cylinders, stemn passages, or the likev What I claim is:-

1. In a force feed lubricating system, a plurality of pumps ha ving plunger-s .con-

nected in sets, the discharge conduits of thepumps of one set being connected with discharge conduits of the pumps of the other set, combined with means for simultaneously moving the pump plungers of the one set in opposite directions, substantially. as and for the purposes set' forth. 2.-Ina force feed lubricating system, c plurality oi'pu'mps having plungers" con: nected in sets the discharge conduits of the pumps of the' one set being connected with discharge conduits of umps of another set combined with means or operating the sai sets of connected plungers in succession, whereby said pumps conjointly deliver oil continuously to several points of delivery under approximately constant pressure.
